The symptoms are that since this morning when I put my laptop into hibernate I've not been able to log into either gnome-shell, gnome-fallback or cinnamon. Each desktop crashes with the error message "Oh no! Something has gone wrong. A problem has occurred and the system can't recover. Please log out and try again."

I can, however, log into & use Mate and a newly created test account does not suffer from the issue. This indicates to me that the problem is local to my account & most likely something to do with gnome3

After much googling, I've not come up with a solution that works for me.

Things I have tried include:Ensuring compiz is not attempting to start on boot.Removal of any gnome-shell or cinnamon extensions/applets that might be causing a problem.Resetting gsettings as described in this bug: https://bugs.launchpad.net/linuxmint/+bug/982051

And much more that I've not documented.

Looking for a little help on where to go from here.

Edit: For the record this LMDE installation is on a Macbook 2,1 that uses Intel graphics that appear to be working correctly.

I attempted the "upgrade" from Nadia to Olivia RC, but somehow botched the cinnamon config causing the same issues upon login. I then installed a "fresh" copy of Olivia RC, forgetting to realize that when it mounted my unformatted /home partition it would keep trying to use the old config files. After deleting that dconf directory it booted right up with no issues.
